I'd rather assess the game on what it is.
Like Martin Robinson of Eurogamer says (one of the few credible reviewers of the driving genre in the mainstream gaming press) it's the most focused, high quality Gran Turismo title since GT3. An outstanding physics engine that compares favourably with Assetto Corsa, an online suit that takes the best from iRacing, and packages it up for a console audience. When you factor in the presentation, photomode and general level of polish, it's no surprise to see GT Sport being praised by those in the know.
Then again, it's all about opinions. For every Martin Robinson there's a Peter Brown at Gamespot, who seem perplexed at the very idea of simulation racing, or why brands like Tag Heuer are even featured. Each to their own.
